Robin had been doing what he usually did most of his days since he joined the Shepherds, studying strategy! To be precise he was going through some old strategies he had used and hadn't worked for one reason or another, and he tried to think why they didn't work.
"Why did I send Ricken to fight that pegasus knight? What was I thinking!?" the tactician pulled from his short silver hair as he dwindled on that glaring lapse of judgment, now he understood why the boy spent a few weeks avoiding him...
"I guess I was sleep deprived..." he mumbled as he made a note to sleep a few more hours, the lack of sleep clearly made him a... dubious mind when it came to strategy.
Robin wanted to keep going through his past tactics but his studying session was interrupted when someone barged into his room, turning his head he saw a familiar face, a woman clad in a gauzy body suit, but unlike most of his interactions with her this time her figure was barely visible due to a large book she was hugging.
"Robin!" the dark mage greeted him and without explaining anything she proceeded to place her large book on his table... on top of the notes he had been carefully studying and proceeded to open it right in the middle, showing some sort of spell he didn't recognize.
"Tharja...?" he asked, hoping that would be enough to get some answers but as usual the plegian didn't answer and just stood there... watching him... without uttering a word... sometimes he wondered why they even started dating.
"I... want..." Tharja finally spoke, she seemed to be slurring her words out almost gasping for air, was that book really that heavy?
"Want to..." she finally continued speaking, her hands now resting on the sides of the book as her eyes scrolled through the open page, "To test... something"
"Test something?" he repeated, immediately getting a bad feeling about the way it was said... he knew her better than anyone in the army but he didn't have to be an expert on Tharja to know how to find her way of hexing people, which made him ask one simple question, "Can you be a little more specific?"
"..." Tharja lifted her eyes from the page and stared right into his own and remained silent, her expression didn't say much... she was frowning, but she usually frowned all the time and the shadow under her eyes was nothing new either... she eventually uttered one word, "No"
Her eyes drifted back to the open page and she lost no time in reading the spell out loud, If Robin had a bad feeling before now he was downright terrified when he noticed a purple gleam emanating from the book.
A gleam that started expanding until it covered the entire room, then Robin felt a pull, almost as if someone were shoving him but more... painful, almost as if he were being ripped away from his own body...
That silly idea suddenly started sounding far less silly when he looked down and saw his body had turned translucent and was slowly being pulled away from his actual corporeal form!
"What's going on!?" the tactician yelled as he tried to cling to his own body but his hand just went through, he noticed his body was unconscious despite standing still but his eyes were... blank, completely white.
"Uhh..." Seeing his body in that... possessed-like state was unnerving and would have certainly sent a shiver down his spine if he could still feel it.
Just when things looked like they couldn't get worse Robin noticed he wasn't alone in his predicament, looking forward he saw Tharja had also turned translucent and was floating above that accursed tome, and for some reason, it seemed like she could move freely.
This ghostly Tharja swam past him, turning around he saw she was now next to his body, the one with the blank stare, and was caressing it... passing her hands through its face and arms, then she decided to hug it and just... vanish.
At that moment Robin felt a suction, a force pulling from him, dragging him away from his body and towards Tharja's, then the world went dark.
---
"Uhh..." As Robin's eyes opened he could tell something wasn't right, the arrangement of the room seemed to have changed, the things he had left on one side of the room were now on the other... in fact, he was standing on the other side of the table.
"What happened..." he mumbled as she rubbed his head, the last thing he remembered was Tharja casting a weird spell on him that turned him... ghostly looking and then... nothing, the whole world went dark.
The... strange experience he had just gone through suddenly became less relevant when he noticed a few locks of dark hair resting on his shoulders, and slightly showing on top of his eyes.
It was this odd discovery that made the tactician look down, and as soon as he did his cheeks turned red as he saw he had... had been turned into a woman, the large breasts on her chest made that apparent, wide hips, thin waist, thick thighs... the missing 'sword' on her crotch.
"What–" Robin tried to say but was interrupted.
"It worked! I can't believe that fool actually had this spell!" Turning her head in the direction of the voice the tactician found herself watching at a... copy of herself.
This other Robin was standing opposite to her, on the other side of the table, and was dressed in her usual attire, a long black coat, white shirt, and baggy pants, but it didn't seem like such modest attire fit her double.
"Robin..." the double muttered his own name as his face turned red, he lost no time stripping out of his cloak, and as soon as the garment fell on the floor this double of him started hugging himself.
"Robin... Robin..." the other tactician repeated between gasps as he started hugging himself, "Yes... I'm Robin... I'm Robin, I'm Robin, I'm Robin!" he could tell he was enjoying himself, the tongue hanging out of his open mouth made that much clear.
Looking at this bizarre... performance made Robin realize something, this other 'Robin' was acting like how she imagined a certain dark mage would act in this situation... and this thought made her aware of what she was wearing.
A gauzy form-fitting bodysuit covered her now feminine physique, a black bra covered her new bust, a long piece of black cloth rested over her crotch in the form of a loincloth, held together by a golden 'belt' tied around her waist, golden circlets adorned her wrists and thighs, a pair of high heels rested in her feet and the only thing she had to cover herself was a long black cape.
"..." Robin's cheeks turned pink as she noticed that, the pieces of the puzzle slowly came together inside her head, her double behavior combined with what she was wearing made what had happened obvious, "I'm Tharja..." she mumbled as she started touching her now black long locks of hair.
"Yes..." who she assumed to be Tharja spoke, he stopped hugging his new figure and managed to recompose himself... or at least as much as he could, his back was bent slightly forward and he had started biting one of his thumbs, "That was the purpose of the spell..."
"What!? You mean you did that on purpose!?" Robin was taken aback by his confession, she had been Tharja's unwilling test subject in the past but this... experiment seemed to be too much, even for him, "Why did you do this!?"
"Hee hee hee hee..." Tharja took his hands to his cheeks as he started giggling, "Isn't it obvious? Because I love you, Robin.."
"You have a really weird way of showing that..." she sighed as she crossed her arms, "Please tell me you can undo this"
"Of course I can, who do you take me for, my dear tactician" The dark mage let out a chuckle as he went back to biting his thumb, "But I won't undo this, not yet at least... we have a lot to experience"
"Tharja I'm not in the mood for your games, I was in the middle of something important before you showed up!"
"Mood... hee hee hee hee, you sure about that?"
As soon as Tharja said that Robin began to feel... weird, her breathing got quicker and shallow and her legs began to shake to such a point that she needed to place her hands on the table.
"W-what–" she tried to mumble but her words died on her throat when she looked at Tharja, as soon as her eyes lay on him she couldn't stop staring at him, had her former body... always looked so handsome.
It might have been a mix of narcissism and being in Tharja's body, but seeing those soft yet masculine faces, those short white locks, that teasing smirk, and that muscular body... now she could definitely understand why Tharja had a thing for her.
"You like what you see, dear tactician?" her thoughts were interrupted when Tharja spoke up, as if he were trying to torture her he walked up to her, allowing her to get a better view of her former features.
"Tharja..." she struggled to get the word out, "W-what did you do!?
"Simple, I put a little hex on myself before swapping with you, one that made me more... excitable," the dark mage said as he wrapped his arms around her "But don't worry it'll wear off after a few hours, in the meantime I know exactly what we should do to kill that time"
"What are–" Before Robin could question what he meant she was silenced when she felt Tharja's lips pressing against her own.
